A remake of the 1987 horror movie of the same name, 2009's "The Stepfather" stars Dylan Walsh, Penn Badgley, Sela Ward, and Amber Heard. David Harris (Walsh) claims to be a family man, seeking out single moms so that he can pair off with them and become stepfather to their children. When the families don't live up to his expectations, however, Harris murders them. In the film, he moves in with a new woman (Ward), but when her son (Badgley) arrives home from military school, the teenager begins to suspect something isn't right.
